Unusual Presentation of Pediatric Scurvy: A Necrotic Gastrostomy Tube Site in a 14-Year-Old Boy.

BACKGROUND Despite being considered a disease of the past, pediatric scurvy is increasingly reported in developed countries, especially among children with autism spectrum disorder, developmental delays, or a restrictive diet. Pediatric patients typically present with lower extremity pain or refusal to walk. This case study features an atypical presentation of scurvy in a non-ambulatory patient. CASE REPORT A 14-year-old boy with arthrogryposis multiplex congenita displayed a late-stage scurvy symptom: a necrotic gastrostomy tube site, indicative of poor wound healing due to vitamin C deficiency. The usual telltale symptoms of scurvy were camouflaged due to his non-ambulatory status, which may have contributed to a delayed presentation. Nevertheless, a comprehensive clinical evaluation, incorporating diet history, gingival symptoms, petechiae, and characteristic radiological signs, eventually led to the correct diagnosis. Although acute osteomyelitis was initially suspected, it was subsequently ruled out. Upon initiation of vitamin C therapy, the patient's symptoms subsided within a few days, and the necrotic tissue surrounding the gastrostomy tube healed completely within two weeks. CONCLUSIONS The highlighted case underscores the importance of including scurvy in the differential diagnosis for pediatric patients with lower extremity pain without fever. A detailed dietary history focusing on vitamin C intake is crucial during clinical evaluation. Early initiation of vitamin C therapy, when scurvy is suspected, may prevent unnecessary and extensive diagnostic workup for other potential causes, offering timely relief to the patient.

Teaching scripts via smartphone app facilitate resident-led teaching of medical students.

BACKGROUND: Previous studies have suggested that resident physicians are the most meaningful teachers during the clinical clerkships of third-year medical students (MS3s). Unfortunately, residents often feel unprepared for this crucial role. The pediatrics clerkship at our institution identified a paucity in the frequency of resident-led teaching with MS3s. Lack of confidence, suboptimal teaching space, and insufficient time were cited as the most significant barriers. To enhance resident-led teaching of MS3s, we created teaching scripts of general pediatrics topics accessible via a smartphone application (app). METHODS: Prior to the implementation of the app, MS3s and pediatric residents were surveyed on clerkship teaching practices. From May 2017 through July 2018, pediatric residents working with MS3s were introduced to the app, with both groups queried on resident teaching habits afterward. We compared pre-intervention and post-intervention data of time spent teaching, teaching frequency, and a ranking of pediatric resident teaching performance compared to residents of other MS3 core clerkships. RESULTS: 44 out of 90 residents (49%) responded to a pre-intervention survey on baseline teaching habits. 49 out of 61 residents (80%) completed our post-intervention survey. Pre-intervention, 75% (33/44) of residents reported spending less than 5 min per teaching session on average. Post-intervention, 67% (33/49) reported spending more than 5 min (p < 0.01). 25% (11/44) of residents reported teaching at least once per day pre-intervention, versus 55% (27/49, p = 0.12) post-intervention. Post-intervention data demonstrated a statistically significant correlation between app use and increased frequency of teaching (p < 0.01). The MS3 average ranking of pediatric resident teaching increased from 2.4 to 3.4 out of 6 (p < 0.05) after this intervention. CONCLUSIONS: Residency programs looking to reform resident-led teaching, particularly of residents early in their training, should consider our novel approach. In addition to addressing barriers to teaching and creating a platform for near-peer teaching, it is adaptable to any specialty or learner level. Future direction includes developing objective measures for teaching performance and content proficiency to better assess our intervention as an educational curriculum, as well as further investigation of the intervention as a controlled trial.

Height Growth Impairment in Children With Neurofibromatosis Type 1 Is Characterized by Decreased Pubertal Growth Velocity in Both Sexes.

Previous studies have suggested that children with neurofibromatosis type 1 are shorter than their unaffected counterparts as an effect of a germline NF1 gene mutation. The pathophysiology of this effect is still uncertain. The purpose of this study was to characterize longitudinal growth in children with neurofibromatosis type 1 in order to assess growth velocity and its influence on stature. Longitudinal height data were collected for 188 patients with a confirmed clinical diagnosis of neurofibromatosis type 1. Children with neurofibromatosis type 1 had population mean heights statistically different from the general population, with a reduced peak height velocity during pubertal growth. In addition, there were no significant differences in the timing of peak height velocity during puberty between the general population and those with neurofibromatosis type 1. These data demonstrate that short stature in neurofibromatosis type 1 is due in part to subnormal height acquisition during puberty.

Severe bilateral adrenal hemorrhages in a newborn complicated by persistent adrenal insufficiency.

Bilateral adrenal hemorrhages rarely occur during the neonatal period and are often associated with traumatic vaginal deliveries. However, the adrenal gland has highly regenerative capabilities and adrenal insufficiency typically resolves over time. We evaluated a newborn female after experiencing fetal macrosomia and a traumatic vaginal delivery. She developed acidosis and acute renal injury. Large adrenal hemorrhages were noted bilaterally on ultrasound, and she was diagnosed with adrenal insufficiency based on characteristic electrolyte changes and a low cortisol (4.2 µg/dL). On follow-up testing, this patient was unable to be weaned off of hydrocortisone or fludrocortisone despite resolution of hemorrhages on ultrasound. Providers should consider bilateral adrenal hemorrhage when evaluating critically ill neonates after a traumatic delivery. In extreme cases, this may be a persistent process. LEARNING POINTS: Risk factors for adrenal hemorrhage include fetal macrosomia, traumatic vaginal delivery and critical acidemia.Signs of adrenal hemorrhage include jaundice, flank mass, skin discoloration or scrotal hematoma.Adrenal insufficiency often is a transient process when related to adrenal hemorrhage.Severe adrenal hemorrhages can occur in the absence of symptoms.Though rare, persistent adrenal insufficiency may occur in extremely severe cases of bilateral adrenal hemorrhage.Consider adrenal hemorrhage when evaluating a neonate for shock in the absence of an infectious etiology.
